AZ31 magnesium alloy, as a typical lightweight and high-strength material, has been widely used in aviation, automobile, electronics and other fields. However, AZ31 magnesium alloy has some difficulties in sheet manufacturing, such as cracking and difficult to control deformation due to material brittleness. Therefore, this research aims to improve the forming performance of AZ31 magnesium alloy sheet and improve the mechanical properties and accuracy of the sheet by using equal-diameter angle rolling method and stamping process.This paper first introduces the structure and mechanical property characteristics of AZ31 magnesium alloy, and the problems that may occur in sheet forming. Then, the principle, experimental design and experimental met...
